To all whom it may concern:

Be it known that I, THOMAS BAKER, a citizen of the United States, residlngat Spokane, in the county of Spokane and State of Washington, have invented certain new and useful Improvements in Reinforced Hollow Brick Walls; and I do hereby declare the following-t0 be a full, clear, and exact description of the invention, such as will enaible others skilled in the art to which it appertains to make and use the same.

This invention relates to a remforced hollow brick wall.

The object of the present invention is to improve the construction of wallsand to )rovide a simple, practlcal and efiicient re- -1nforced hollow brick Wall adapted to lighten the construction and enable the wall to be constructed of less material and at the same time exclude molsture, cold and heat.

drawing and pointed out in the claim hereto appended; it being understood that various changes in the form, proportion, sizeand minor details of construction, within the scope of the claim, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing:

Figure 1 is a perspective view of a .portion of a hollow brick reinforced wall constructed in accordance with this invention.

Fig. 2 is a transverse sectional view of the same. 1 i Fig. 3 is a detail view of one of the half or corner'bricks shown in Fig. 1.- Like numerals of reference designate corresponding parts in all the figures of the drawing.

In the accompanying drawing, in which is illustrated the preferred embodiment of the invention, the reinforced hollow brick wall, which may be constructed of two, three or four inch brick, or in fact brick of any desired size, is composed of a plurality of wallsections or members, inner, intermediate and outer sections 1, 2 and 3 being shown in Fig. 1, but'the number of wall sections or members may of course be varied to provide a wall of'the desired dimensions and strength to suit requirements. The wall provided with openings 5 preferablylocated at the center and ends as shown and, when the wall sections or members are made up of a single tier o'r brick or a thickness equal to-the width ofa brick, half bricks 6 having central openings 7 may be employed but the size of the bricks and the thickness of the wall sections or ,members may be of course varied, as will be readily understood, Y

, 'lllie brick are laid in layers or coursesthe ordinaryv manner and the wall sectlons or members are tied to ether at every five or. six or seven courses fiy tie bricks 8 of twelve'inches in length or of sufiicient length to span the spaces 9 between the parallel sections or wall" members 1, 2 and '3, and the said tie bricks 8, which may be of any desired length, are provided at their end portions with openin 10 adapted. to register with openings 0 the bricks 4 or 6, as clearly illustrated in Fig; 2 of the drawing. The transversely disposed tie as shown and they are located at regular intei'vals and their openings, which are filled w1t h mortar keys 11, are arranged to receivedowelpins 12- constructed of steel or other suitable material and which pass through the openings of the transversely disposed tie bricks and project wardly beyond the same so as to extend into the openings of the adjacent bricks 4' or 6,to provide amechanical bond between the vertical wall sections or members. The projecting terminals of the dowelpins engage the mortar in the openings of the bricks of the wall sections or members, the laying of the bricks in the usual manner filling the upper portions and lower portions of the bricks of the wall sections or members, as shown. By this construction, the dowel pins will be embedded in the mortar and will firmly tie the wall sections together. When the transversely dis osed tie bricks 8 are arranged at their a jacent ends upon each' other as shown in Fig. 2, an elongated dowel pin 13of suflicient length toextend through both of the tie bricks and. project'beyond the same to engage the adjacent bricks of,

and by reason of the said spaces less maupwardly and 'downteri-al will be employed in the construction of the Wall and a lighter construction Without any diminution in the strength of the wall will be provided. Also the dowel pins provide a reinforced Wall and a mechanical binding between the Wall sections or members. The number and size of the openings o fthe bricks may be varied and the structure is applicable to Walls of various thicknesses.

What is claimed is:

A Wall comprising inner, outer and intermediate spaced parallel sections, each section including superposed layers of blocks; pairs of transverse stretcher blocks having their inner end portions overlapping vertically and mounted in the intermediate secpins embedded in said mortar keys and connecting the end portions of the stretcher blocks and the upper and lower adjacent blocks of said sections.

In testimony whereof I aifix my signature in presence of tWo Witnesses.
